Electra Elite IPK II
Description
Uniform Numbering Network allows multiple or compatible systems to be connected in a network using
Tie Lines. A station user can dial a system number and a station number (open numbering) or dial the
station number only (closed numbering) to access any station. When the calling and called systems are
not directly connected, several Tie Lines may be accessed to route the call. Each system extends the
call to the next system until the final destination is reached. Networking provides a seamless connection
of multiple systems into a single "virtual" communications system using Tie Lines with a unified
numbering plan. Networking will allow many companies to connect their telephone systems so they
appear as one. An extension user in the network can easily dial another extension or transfer a call
within the Networking System. Calls are passed from network node to network node using a protocol
that contains information about the source of the call, the type of call and the destination of the call.
Flexible Network Routing
Use network routes to set up "single channel" networking between many separate systems – or use
multiple networking channels per system for greater network performance. Data tables in the system
program define the routing for each extension in each network node. These tables are easily customized
to meet the requirements of each networking configuration. Users may place an intercom call or transfer
a call to any extension at any location by simply dialing an extension number. The system analyzes each
extension number received and determines how to route the call to its final destination. The feature
which handles this route selection is called Flexible Routing (F-Routing). F-Routing also has the ability to
select alternate routes to the destination extension if the primary destination is busy. Up to 120 routes
are available for networking. Once an extension number is dialed, the system checks the routing,
accesses the assigned trunk group and places the call. Each extension is assigned a route or routes that
decide which trunk group to access and any modified dialed data if required.
Conditions
Monitor the Uniform Numbering Network Access Code plan to avoid loss of Access Codes
r
and to prevent duplicating codes.
r
The distant system number can be programmed as 2~8 digits in length.
The Electra Elite IPK II system has 500 ARS/F-Route Tables that can be shared by
r
outgoing Tie lines, ISDN CO/PBX, and FT1 lines.
